原则2平原价值预期
问题描述:
我无法执行Doctrine DQL查询。这是它给我的错误。
I'm having trouble executing a Doctrine DQL Query. This is the error it gives me.
Doctrine\Common\Annotations\AnnotationException: [Syntax Error] Expected PlainValue,
got 'integer' at position 13 in property Base\Session::$lifetime.
我的代码如下所示:
$query = $em->createQuery("SELECT s FROM Base\Session s WHERE s.session = \"$id\"");
其中$ id是当前session_id。我的模型看起来像:
Where $id is the current session_id. My Model looks like:
namespace Base;
/** @Entity @Table(name="session") */
class Session extends Skeleton {
/**
* @Id @Column(type="integer")
* @GeneratedValue(strategy="AUTO")
*/
protected $id;
/** @Column(length=32) */
protected $session;
/** @Column(type=integer) */
protected $lifetime;
/** @Column(type=integer) */
protected $modified;
/** @Column(type="text") */
protected $data;
}
答
您有两个错误
- 您必须引用您的注释,即@Column(type =integer)而不是@Colunn(type = integer)。当您的Mapping错误时,Doctrine\Common\Annotations\AnnotationException被抛出。这与查询无关。
-
您的查询应使用准备好的语句,即
- You have to quote your annotations, i.e. @Column(type="integer") not @Colunn(type=integer). Doctrine\Common\Annotations\AnnotationException is thrown when your Mapping is wrong. This has nothing to do with the Query.
Your query should use prepared statements, i.e.
$ query = $ em-> createQuery(SELECT s FROM Base\Session s WHERE s.session =?1);
$ query-> setParameter(1,$ id);
$query = $em->createQuery("SELECT s FROM Base\Session s WHERE s.session = ?1"); $query->setParameter(1, $id);
